IMPROVEMENT lN MACHINES FOR DRESSING YARN.

Speciiication forming part of Letters Patent No. 33,222, dated September3, 1861.

To @ZZ whom it may concern.:

Be it known that I, HUGH WHITEHILL, of Newburg, in the county of Orangeand State of New York, have invented certain new and useful Improvementsin Machinery for Dressing Yarn; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of thisspecification, in which- Figure l represents a plan or top View of myinvention. cal section of the same. dinal section of theslotteddressing-cylinder.

Similar letters of reference indicate corresponding parts in the threefigures.

This invention consists, first, in the employment of a reed of peculiarconstruction, being made of a solid longitudinal center bar which keepsthe two sections of the yarn separate, and being provided withspring-bars on top and bottom to prevent the yarn jumping over theupright rods of the reed; second, in a mode of regulating the speed ofthe dressing-brush by the speed of the yarn itself, so that thedisadvantages generally arising from a varying speed of the yarn inregard to the brush are avoided; third, in the employment of aflutedsteam-cylinder for the purpose of avoiding the baking or overheating ofthe yarn if the dressing-frame is stopped.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

The yarn as it is delivered to the dressingframe from the rollers A Bpasses through a reed O, provided with a longitudinal central rod ct,which separates the two sections of the yarn. Each section of the reedis protected by a spring-bar b, which rests on the partition-rods c ofthe reed, and which prevents the yarn from one partition passing over tothe other. l If one of the strands breaks While the frame is running, itcan easily be lifted over the partition-rod by pushing the spring-bar upfor the upper and down for the lower section of the reed, and saidspringbars always resume their original position by the force of thesprings acting upon them. In leaving the reed the yarn goes over theroller D, around the size-rollers E F, and over the dressing-brush G totheroller H, the several Fig. 2 is a longitudinal verti- Fig. 3 is alongitu strands being kept apart by means of a reed C', similar in itsconstruction to the reed C, but without the spring-bars. rl`he brush Gismade out of several sections attached to arms d, as clearly shown inFig. 2 of the drawings, and as the brush rotates one of its sectionsafter the other is brought in contact with the yarn passing along overthe same. Bythese means the yarn has time to recover between thesuccessive actions of the several sections of the brush, and it (theyarn) is therefore less liable to break and become deranged than wheneX- posed to the continuous action of the usual brush-cylinder. Inpassing over the roller H the yarn imparts to the same a rotary motion,and a pulley c, which is secured to the axle of said roller, serves totransmit its motion to the brush G by means of a belt f, which extendsfrom the pulley c over a pulley g on the axle of the brush. By thisarrangement the speed of the brush is regulated entirely by the speed ofthe yarn, so that a uniform action of the brush on every portion of theyarn is effected. From the roller I-l the yarn is conducted to theslotted dressing-cylinder I, which rotates on stationary flanged disksJ, and which is furnished with a steam-coil K. This coil passes throughthe disks J to the interior of the cylinder, and it occupies the spacenear to its inner surface, as clearly shown in Fig. 3 of the drawings.In the center of the cylinder and attached to the shaft L is thefan-blower M, to which an independent and quick rotary motion isimparted by means of a pulley N on one end of the shaft L. By thisarrangement a blast of hot air is thrown against the yarn stretched onthe out` side of the cylinder I. From the cylinder I the yarn passesover a roller I to the cylinder O, which is heated by steam in the usualmanner; but instead of making the surface of this cylinder smooth Iemploy a tluted cylinder, so that the currents of cold air are allowedto pass between the yarn and the heated surface of the cylinder, therebypreventing a baking of the yarn if the dressing-frame is stopped.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The arrangement of the reed C, consisting of alongitudinal centralrod ct and vertical partition-rods c, in combination with sprng- 3. Theemployment of a steam-cylinder O bars b, substantially as and for thepurpose with a fluted surface, as and for the purpose described. setforth.
